50/month giving with 2% annual uplift over 40 years = roughly 36,200 lifetime giving. Consistent small amounts create substantial aggregate impact over a lifetime.
Quick example
With monthly giving of 50 and annual uplift of 2% (plus years of 40 years), the result is 36,241.19. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Monthly Giving, Annual Uplift, and Years. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
What's happening under the hood
Annual × 12 compounded at uplift rate. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Reading the result without judgement
The figure isn't a scorecard. It's a prompt — something to sit with for a few days before deciding whether any habit needs changing. Reflexive reactions ("I need to cut everything") usually don't last; considered ones do.
What this doesn't capture
Behaviour-adjacent math is always an approximation. Human habits are lumpy and context-dependent; the figure here assumes steady behaviour which is a simplification. Treat the output as a prompt for thinking rather than a precise prediction.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the alcohol lifetime cost calculator, the lunch out lifetime cost calculator, and the smoking lifetime cost calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
Total lifetime charitable giving is shown above.
