For nannies
More to earn. More to bring.
More earning potential, and steady work as families come and go. More personalities and more possibilities for the day: room to turn a small group into a world of discovery.
The app for nanny shares.
A nanny share at its best.
Kids who learn to share and get along. A nanny with time for each child and fair pay for every hour. Families who split the cost and feel part of every day.
Good intentions and rules of thumb only go so far. With a quick tap from each adult, Sharefully keeps the story of each day and the math behind it, so nothing rests on memory, and the share runs smoothly, year after year.
Built from eight years of nanny sharing.

Payday
Some weeks don’t add up.
A late handoff that never made it into the hours. An extra afternoon remembered differently. A payment that seems a little short.
The first time, it’s easy to just let it go. By the third payday, they’re still letting it go. But they haven’t forgotten, and raising it now means raising all of it.
Nanny sharing was good on paper, until one day it just wasn’t.
A nanny share can run on understanding.
Shares that last are built on small details done right. Sharefully makes those details automatic, so every week adds up, and nobody has to sweat the small stuff.
The nanny share rate
Fair pay starts with one hour.
Ask about nanny share pay in almost any parents’ group, and someone mentions the two-thirds rule: each family pays about two-thirds of the usual rate. A nanny at $24 an hour on your own costs each of two families $16, a third less. Hourly pay for the share is $32, a third more.
That works when each family has one child and every hour is shared. Real shares rarely stay that tidy.
A third family joins. Or one family has two children. Or one child goes home after lunch, and the other stays. Who pays what for those hours? Double? Half again? Nobody wants to be the one to ask.
The Fair Share Rate Calculator by Sharefully works it out, one hour at a time. It starts with one family and one child. Change any number to match your share.

Splitting the rate can feel fair.
From one hour to the whole week
With Sharefully, the week adds up.
One hour is one thing. A real week is another. Juno is home all day. Wren is at preschool most mornings, but Family A still pays for those hours. Theo joins after lunch. One evening runs late, and the time gets added later from memory.
Every hour has its own split. By Friday, that’s dozens of small calculations, and a lot to remember.
It stays easy when each handoff is recorded as it happens. Sharefully adds up the rest.
One week, start to finish.
The rates above, applied to a two-family example week.
The nanny or the parent records each handoff as it happens. The other adult confirms it with one tap.

Overlapping times make the math hard. Sharefully splits every hour by who was there, so the total pay and each family’s share always agree.
All families
No hour is counted twice. Every hour of care is paid once. When children from both families are together, each family pays its part of that same hour, so the two families’ hours add up to more than the hours of care.

Familiar care. A friend beside them.
A familiar face each morning. Attention to their own little rhythms. A companion for the sandbox, taking turns, and learning to be together.
For families
Care at home. Community around it.
Personal care at home, with the cost shared. Children making friends and families becoming a community, with backup plans they can make together.
Be shareful
Sharefully started with two words from our first nanny.
Our first nanny cared for two small children from our two families. When both reached for the same toy, she said it the way you would say be careful, soft and certain:
“Be shareful.”
It was a lesson for the children: a way of playing and being together. And she lived it herself. She kept a notebook of each day, and every evening at the handoff she shared it with both families, so we parents, away all day, could feel a little like we’d been there too. Nobody asked her to. She was shareful in everything she did.
Her words and actions matched, and that inspired me to make the pay just as shareful. It started as a spreadsheet: what she earned, and each family’s fair part, which we each took to our own payroll service. Its job was to make the numbers make sense, to her first and then to both families. Years later, after a move, our second nanny cared for our kids through three shares with four other families. Each new arrangement meant redoing the math, and the spreadsheet grew into a weekly calculator app. Getting it right felt like a responsibility. It also reminded us that we were all in the share for the same reason: our kids. I built Sharefully to make running a nanny share easy, clear, and above all fair for everyone in it.
Max, founder
She taught our kids to be shareful. Sharefully is the notebook every nanny deserves: each day co-authored with every family, and the hard math built right in.
You probably have a few questions.
- Do we have to change payroll?
- No. Sharefully calculates the week and each family’s part. You keep your payroll service.
- What if it’s just one family and a nanny?
- Sharefully works there too. Every family with a nanny has handoffs to record, hours to agree on, and a week to get right. A nanny share just has more of it to keep straight.
- Does everyone need to use it?
- It works best when everyone does: the nanny confirms the week, and each family approves its part. Day to day, it’s a quick note and a one-tap reply. Each person joins by choice.
- Who sees what?
- Everyone in your nanny share sees the same week record. Each family can keep a lot of its own information private, but anything that affects another family’s pay is shared and visible.
- What does it cost?
- The calculator is free. Pricing for the app isn’t set yet.
- Do you work with nanny agencies?
- Sharefully is built for families and nannies first. If your agency places nanny shares, join the waitlist as an agency and tell us how you work. Your answers help shape what we build. We can’t promise agency features yet.
- Can we use it now?
- Not yet. Leave your email below, and we’ll let you know when it’s ready.

Notes and caveats
The calculator and the example week keep their notes short. Here is the longer version, in one place: what they assume, how they round, and what they leave to you and your advisors.
The calculator
The calculator works out one hour of care, not a week of pay. It leaves out overtime, taxes, benefits and paid time off.
The rates are yours. Each nanny share agrees on its own rates, and Sharefully does not set them. The figures are not wage advice.
The single-family rate and the extra-child amount are what one family pays for dedicated care. With two or more families, hourly pay builds on them with the share rate rule you set (two-thirds is the most common). That is what each of two families pays for one child each, as a share of the single-family rate.
Each family’s part is sized by a family factor, plus a child factor for each of its children. The calculator shows both amounts for your numbers.
The extra-child amount has a limit. With the two-thirds rule, it must stay under a third of the single-family rate. With the 70% rule, it must stay under 40%, and with the 75% rule, under half. Within that limit, adding a family always raises hourly pay, and a sibling never counts for more than a family’s first child.
The lower the share rate rule, the lower that limit: at 60%, it’s a fifth of the single-family rate.
The calculator works with exact amounts and rounds each figure it shows to the cent. Because each part is rounded on its own, the families’ parts can differ from the total by a cent or two.
The example week
The names are fictional. The week is based on a real one, from the founder’s own nanny share.
Family A has guaranteed mornings: time it reserves for care, whether or not its child comes. Unused guaranteed time counts as if Family A’s child were there, and Family A pays its part, as in the founder’s own share. That time is paid, but it is not counted as hours worked.
The week uses the rates from the calculator. It always has two families, so the two-family limit on the extra-child amount applies, even when the calculator is set to one family.
Overtime is worked out for each family on its own: hours over 40 worked for that family in a week, at 1.5 times that family’s rate. That is one convention, not the only one. The rules where you live may count hours differently.
Hours and rates are rounded up to two decimal places, so pay is never short.
Employment and the law
Sharefully does not run payroll or move money, and nothing on this website is legal, tax or payroll advice, or a statement of what any law requires.
Minimum wage, overtime, paid leave and tax rules vary by state and city.
Whether the families in a share are joint employers of the nanny depends on the state and the facts.
Caring for children from several families may require a childcare license in some states.
Before you use any figure to pay someone, check it with your payroll service or an advisor.
Shares with three or more families
The calculator’s arithmetic goes up to five families, with up to five children each. That is a limit of the math, not a recommendation.
How many children one caregiver can look after safely depends on their ages and needs. Young children need more hands. Agree on a limit together, and check local rules, which may set limits of their own.
